Re: question to mixed CP an IFL in one LPAR
Rcihard S. and Ray M. both point out situations where having the LAPRs be IFL-only or CP-only ones is not feasible, or desirable, for a number of reasons. In these situations, having the ability to mix-and-match engines in an LPAR is a good thing. I just wish we didn't have to deal with all of this silliness of different types of engines in the first place. Sigh Have a good one.

PERFKIT showed that almost all of the work was being dispatched on the fractional CP with the IFL basically idle. The fix was to remove the CP from the LPAR definition, making it, as Alan notes, it Linux only. IMHO, unless there is a clear cut need to combine CPs and IFLs in a single LPAR(so, e.g., to run z/OS as a guest), it's best not to do so.

New standard for networking help
I have to tell you all that my hopes have been renewed, my spirit uplifted, and my faith in mankind restored. A customer asked for assistance with a networking problem. With that request was a 17-page document that contained: - A table of contents with 3 heading levels of detail - A drawing of the network, logical and physical, with IP addresses and subnets, and MAC addresses (virtual and real). Color-coded. - OSA card configuration and port/adapter status, with screen shots of the OSA Advanced Facilities output. - Queries showing software levels of z/VM and Linux - AUTOLOG1's PROFILE EXEC and SYSTEM CONFIG - Directory definitions - Linux PROFILE EXECs configurations, including ifconfig and lscss - Ping results (inbound and outbound) - QUERY VSWITCH and QUERY NIC results All output from CP and Linux was shown nicely pasted into frames with easy-to-read colored backgrounds and no wrapping. Commentary was provided with appropriate use of arrows and contrasting colors (e.g. red = unexpected results). Boldface type was used to emphasize those pieces of output the customer thought was relevant. In short, a work of art that brought tears of joy to my eyes The respect this document showed for the reader cannot be understated! (I am thinking about placing it in the VM Hall of Fame.) Bottom line, it enabled me to discover the problem in about 5 minutes - the NATIVE and default VLAN on DEFINE VSWITCH had the same value. My friend, Chuckie, whispered to me that all World-Class Systems Programmers would undoubtedly like to know about and adhere to this new Standard of Excellence, so I immediately thought of you all. :-) I admit to being anxious to see how others will improve upon this standard (such as by including chocolate)!

Re: Devices OFFLINE at IPL
We have been using class V for years to allow the TPF guests to be able to find an available Security Module and ATTACH it to themselves. They do not get DETACH because then they could wreak havoc by detaching from other guests and from SYSTEM. Class V also gets the ability to use class B QUERY commands. Nobody outside the VM Systems group and the operators has either class B or C. The normal is class G for those who are not set up for TPF testing; GV for those who are. The only MVS types who even have ids on the system are those who must deal with the hardware configuration. Giving them anything but GV would make me nervous as they may log on once or twice in a year. Their VM skills are not finely honed.

Alan, Thank you for your expeditious response. In look back, I see that the LINK statement in MAINTs directory entry was commented out for 5VMPTK40.200.

Another possibility is to use the loadparm with a system config file name in it which is useful if you have PPRC'd dasd and have switched the primaries and secondaries and perhaps they aren't back in sync yet and duplicate volumes would cause issues.

Re: Devices OFFLINE at IPL
The drawback to Mike's approach is that your system name changes at your DR site. True... but I *like* and *use* the different System_Identifier names! That would cause more problems than it would solve for us. Perhaps, but when it is planned for it can be a huge benefit... (aside from users knowing that they are running on a D.R. system, and perhaps not expecting any changes to remain after the test is completed). The System_Identifier from SYSTEM CONFIG is easily returned from rexx code: parse value diag(08,'QUERY USERID') with self . ConfigSysID . '15'x . Note: The CMS command IDENTIFY returns the nodename from SYSTEM NETID S2, not necessarily the same. This permits service machines to take different code paths when running on (e.g.) VMPROD vs 'RECOVERY or VMTEST (2nd level). Perhaps during D.R. certain service machines will use different hardware addresses, not start some applications, or start other ones. Examples include VTAM, and TCPIP. When those servers come up here, they read NODAL CONFIG Y2, and respond accordingly when matching the System Config System_Identifier (node names have been changed below to be more obvious): ---snip--- * This file is read by various REXX and GCS programs for use in * normal operations and in disaster recovery both in Lincolnshire and * at a disaster recovery vendor. *SysCfgID Svm_Name Dtyp Rdev Comment * CPC4 LPAR2 as of 20090214 PRODVM VTAM CTCA 0D61 'CTC 0D61 to SYSE, Read1' PRODVM VTAM CTCA 1D61 'CTC 1D61 to SYSE, Read2' PRODVM VTAM CTCA 0D62 'CTC 0D62 to SYSE, Write1' PRODVM VTAM CTCA 1D62 'CTC 1D62 to SYSE, Write2' PRODVM TCPIPOSA 0140 0140 PRODVM TCPIPOSA 0141 0141 PRODVM TCPIPOSA 0142 0142 * CPC4 LPAR2 as of Feb 2008?

After all: the sysprogs may have been casualties during the disaster. OK, we *do* have to install a few product passwords for D.R. serial numbers, but that is well documented, and pretty minimal (newer contracts have stricter ISV requirements allowing us to run on any of our machines). Hardware differences when running on the bare metal (done when recovering from our other data center) can be taken care of programmatically in this manner without requiring manual intervention, and without running VM under VM (making appropriate directory changes just to get the same device addresses as prod). Creating the NODAL CONFIG Y2 file above meant that when hardware addresses are changed, I don't have to search all over the place to find references to those addresses - they are all in one place. As usual, YMMV. After years of tweaking to speed up our D.R. (more or less, the Operator IPLs VM from the recovery machine, responds to a prompt from an EXEC called by OPERATOR's PROFILE EXEC asking if they really do want to IPL on a machine with a different serial number. Then the system comes up automatically adjusting for the processor change and it's particular hardware addresses and own peculiarities. During D.R. (after the mirrored and remote-copied DASD has been cut and the network is up), once we are given the LPAR for VM, the VM IPL takes the same 7-10 minutes it normally takes, and does not require a VM sysprog. Of course, we're always standing by in case something breaks, but this really does take all the work out of it at zero-dark-thirty.
